Subject: misc: sram: remove redundant null pointer check before of_node_put
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3104389edc012e2567cabb94af8763121c33e72b;p=openwrt%2Fstaging%2Fblogic.git

misc: sram: remove redundant null pointer check before of_node_put

of_node_put has taken the null pinter check into account. So it is
safe to remove the duplicated check before of_node_put.
